The Gastro-Laringeal Tube for interventional endoscopic biliopancreatic procedures in anesthetized patients.

The Gastro-Laryngeal Tube (G-LT) is a modification of the laryngeal tube which provides a dedicated channel for the insertion of an endoscope while acting as a supraglottic airway for ventilation. The aim of this study was to assess the safety and effectiveness of this device in patients undergoing anesthesia for interventional endoscopic biliopancreatic procedures (IEBPPs). A total of 22 patients were included in the study.The G-LTwas inserted successfully in all patients. Arterial oxygen saturation was stable; the mean value was 97.9 %. The IEBPPs were performed successfully in all patients through the endoscopic channel, with a mean duration of 99 minutes. The maneuverability of the endoscope was considered good in all patients. There were two cases of sore throat after the procedures, two cases of asymptomatic erosion of the upper esophageal mucosa, one case of Mallory–Weiss syndrome, and one case of pancreatitis after endoscopic retrograde cholangiopancreatography. Our results suggest that the G-LT is an effectiveand secure device for airway management and for use during IEBPPs.
